malleable

A term applied to a metal capable of being beaten or rolled in all directions without breaking or cracking. Since the molecules of the metal must remain locked to each other during the beating or rolling, a malleable metal must exhibit a high degree of structural plasticity. The most malleable of all metals is gold, which can be beaten into a sheet (leaf) only 1/300,000 inch thick. Other malleable metals used in bookbinding include silver, aluminum, platinum, and palladium. (233 )
